Document Type and Number:
Japanese Patent JP6815089
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a storage container easily separable when overlapped without largely changing a shape of a specific pleat.SOLUTION: A storage container 5 comprises a circular-shaped bottom part 11 integrally formed by press-molding a circular sheet-like molding object and a sidewall part 12 of the same height of continuously forming n (n is a natural number of 2 or more) pieces of pleats 9 extending upward over its whole periphery by standing up outward-upward from the outer periphery of the bottom part 11, and has n-time rotation symmetry in a plan view, in which a pleat angle being an engle formed by both-side fold lines for constituting the pleat to the center S of the bottom part 11 in a plan view on a certain pleat, is made different from the pleat angle of at least its other one pleat, and thus, has (n-1) time rotation symmetry at most in a plan view, and when overlapping the storage container by rotating the certain pleat for several minutes, a mutual-pleat-noncoincident state is caused between the upper-lower storage containers.SELECTED DRAWING: Figure 1
